No. 447,219 12 Claims. (Cl. 156-538) ABSTRACT OF THE DISCLGSURE An apparatus for applying outside heads to the ends of paper rolls in which said paper rolls are rolled along a ramp which terminates at a transverse pivoted roll supporting beam forming a mounting means for movable suction header platens movable toward and from a paper roll on said beam. Two cylinders and cooperating pistons are mounted for pivotal movement about coaxial axes to tilt the beam into roll receiving, holding and discharging positions wherein one of said cylinders and its cooperating piston is larger and has a shorter stroke than the other cylinder and its cooperating piston, and serves to hold the beam in its roll supporting position.

This invention relates to improvements in roll headers and more particularly relates to an improved form of header apparatus for applying the outside heads to wrapped rolls of paper and the like.

A principal object of the present invention is to provide a novel and improved form of apparatus for applying the outside heads to wrapped rolls of paper and the like, arranged with a view toward utmost efficiency in operation and simplicity and compactness in construction.

Another object of the invention is to provide an improved form of header platen for applying an outside head to the end of a partially wrapped roll of paper, in which the platen retains the head to be applied to a roll of paper by the creation of streams of high velocity air in confined regions along the outer face of the platen to create suction through the air orifices of a bafile, extending over the high velocity confined flowing streams of air.

Another object of the invention is to provide an improved form of apparatus for applying outside heads to the ends of wrapped rolls of paper, in which the rolls of paper roll to a header apparatus along an inclined ramp to a transverse beam having roll retainer rails extending therealong, in which means are provided for tilting the beam to position the advance rail to form a continuation of the loading ramp to receive a wrapped roll of paper and retain the roll from further travel, for tilting the beam into an upright position to hold the roll of paper in position to have outside heads applied to opposite ends thereof, and into a discharge position to tilt the rails and roll the roll of paper from the beam, for storage or further processing.

A further object of the invention is to provide an improved form of apparatus for applying outside heads to wrapped rolls of paper and the like, in which the rolls of paper roll to the apparatus along a loading ramp and in which the loading ramp terminates at a transverse pivoted roll supporting beam, forming a mounting means for movable header platens movable toward and from the roll of paper on the supporting beam, and in which two cylinders and pistons mounted for pivotal movement about coaxial axes are provided to tilt the beam into roll receiving, roll holding and roll discharge positions, and one of the cylinders and pistons is operatively connected to the beam by a pin and slot connection and is larger and has a shorter stroke than the other cylinder and piston, and serves to hold the beam in a roll supporting position and to limit the stroke of the other cylinder and piston when the beam is in its roll supporting position.

3,468,247 Patented Oct. 29, 1968 A still further object of the invention is to provide an improved form of header for applying the outside heads to rolls of paper and the like including a beam positionable into roll receiving, roll holding and roll discharging positions and carrying carriages therein movable toward and from a roll of paper supported on the beam, wherein the carriages provide supports for header platens extending above the beam for retaining heads thereto on the suction principle for application to opposite ends of the roll of paper, and in which the beam, the means for tilting the beam and moving the carriages toward and from the roll of paper may all be recessed below the level of the loading ramp for the roll of paper.

These and other objects of the invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings wherein:

In the embodiment of the invention illustrated in the drawings, I have shown in FIGURES l and 2 a heading apparatus for applying paper or cardboard outside heads to the ends of wrapped rolls of'paper and completing the wrapping operation thereof. The heading apparatus includes generally a header platen 10 supported on a carriage 11, mounted within a beam 12 forming a forward continuation of a loading ramp 13, which may be inclined downwardly toward the beam at a slight angle, to accommodate a wrapped roll of paper (FIG- URE 6) to roll onto the beam 12 and be supported by said beam for the application of heads to opposite ends thereof by the header platens 10. The carriage 11 and header platens 10 are movable along the beam from 0pposite end portions thereof toward the center of said beam into engagement with the ends of the wrapped roll of paper, for applying heads thereto. A discharge ramp 14 extends from the opposite side of the beam 12, to support the roll of paper to be carried for use or to a labeling or storage station.

The beam 12 is mounted at its opposite ends for pivotal movement about an axis extending transversely of the ramp 13 on upright standards 15. For convenience in illustration and description of the invention only one standard is herein shown and described, The standard 15 is mounted at one end of a base 16 extending beneath the ramp 13 and below floor level. Each standard 15 has a block 17 mounted on its upper side and projecting upwardly therefrom and having a semi-circular upwardly opening recess 18 therein forming a support for a roller 19, journalled on the outer end of a shaft 29 mounted in and projecting outwardly on an end Wall 21 of the beam 12 (FIGURE 5). The recesses 18 in the blocks 17 and the rollers 19 on the shafts 20 thus form 3 a pivotal support for the beam 12 supporting the beam for pivotal movement about an axis disposed closely adjacent the supporting surface of the ramp 13, and extending transversely thereof.

The beam 12 is shown in FIGURE 2 as comprising two spaced channels 23 mounted on and extending al ng opposite sides of a bottom plate 24 and upwardly of said bottom plate. The channels 23 are connected together at their opposite ends by the end plates 21, and the upper flanges of said channels form supports for plates 25 extending therealong and having roll supporting rails 26 mounted thereon and extending upwardly therefrom. The rails 26 may be made from hard wood or a like material to avoid damage to the wrapper extending about the roll of paper, and are inclined downwardly from their outer ends to the inner ends of the plates 25 at the average contour of a roll of paper placed thereon to retain the roll of paper in position to have an outside head applied thereto. The plates 25 stop short of the center of the beam 12 and their inner margins form a slot 27, through which extend spaced support plates 29 for the header platen 10. The spaced support plates 29 extend upwardly of the carriage 11, mounted for movement along the beam 12, and are welded or otherwise secured to a frame structure 33 of said carriage.

As shown in FIGURES 1, 2 and 5, the carriage 11 13 supported within the beam 12 for movement therealong on rails 35 extending along the insides of the webs of the channels 23 of said beam and inwardly therefrom, parallel to the base 24. Pairs of upper rollers 36 at opposite ends of the frame structure 33 are supported on the top surfaces of the rails 35 and support the carriage for movement along said rails. Retaining rollers 37 engage the under surfaces of the rails 35 and retain the carriage in position on said rails, free from tilting movement with respect to said beam. The rollers 36 are mounted on opposite ends of the carriage frame structure 33 on shafts 40, 40 while the rollers 37, disposed beneath the rollers 36, are mounted on opposite ends of the carriage frame structure 33 on shafts 41, 41.

The frame member 33 is likewise provided with spaced horizontally disposed rollers 43, 43 engaging the inside of one rail 35 and mounted on the carriage frame member 33 on vertical shafts 44 mounted at their opposite ends in the carriage frame structure and supporting the rollers in a recessed portion 45 of the carriage frame member 33. A single roller 46 is mounted in the recessed portion 45 for engagement with the opposite rail 35 to retain the carriage in alignment with the beam 12 when moving therealong. A bifurcated drive ear 48 depends from the inner end of the carriage frame member 33 and is bolted or otherwise secured thereto and extends along opposite sides of a connector 49 on the end of a piston rod 50 extensible from a cylinder 51. A pivot pin in the form of a nut and bolt 53 is provided to connect the connecting ears 48 to the connector 49. The cylinder 51 may be a double acting air cylinder, mounted at its head end at an outer end of the beam 12 on a mounting member 55 and extending inwardly along said beam. Fluid under pressure, such as air, may be admitted to the head and piston rod ends of the cylinder 51 under the control of suitable valve means (not shown) to move the carriage 11 and header platen along the beam 12 toward and from the end of a wrapped roll of paper on the support rails 26, 26.

A means is provided to hold the beam 12 and retaining rails 26, 26 in a roll supporting position, and to tilt said beam to position the top surface of an advanced rail 26 to form a continuation of the loading ramp 13 and to position the opposite rail 26 into position to be engaged by the roll of paper and stop travel thereof, and,

also-to tilt the beam 12 in an opposite direction to eject a wrapped roll of paper having outside heads applied to the ends thereof, onto the discharge ramp 14 for labeling or further treatment.

The means for tilting the beam 12 and holding the beam in its various position is shown in FIGURES 2, 4 and 6 as comprising two cylinders and pistons 56 and 57, one being pivotally supported on the base plate 16 at each end of the beam 12. The cylinders 56 and 57 are diagrammatically shown in FIGURES 2 and 6 as being mounted one above the other for convenience in illustrating the invention. The cylinders 56 and 57, however, are mounted for pivotal movement about coaxial axes as may be seen in FIGURE 4. The cylinder 56 is shown in FIGURE 4 as having trunnion pins 59 extending from its head end and pivotally mounted in support brackets 60 mounted on and extending upwardly of the base plate 16. The cylinder 56 has a piston (not shown) therein having a piston rod 61 extensible therefrom having a connector 62 on the outer end thereof transversely pivotally connected to the beam 12 adjacent the lower end thereof on a pivot pin 63, pivotally mounted between connector ears 64 extending outwardly from the lower end portion of the beam 12. The cylinder 57 is of a larger diameter than the cylinder 56 and has connector ears 65 extending from the head end thereof along opposite sides of a connector bracket 66 mounted on the base plate 16 and extending upwardly therefrom. A pivot pin 67 coaxial with the trunnion pins 59 is provided to pivotally connect said cylinder to the connector bracket 66. The cylinder 57 has a piston rod 69 extending from a piston (not shown) movable within said cylinder and having a connector 70 on its outer end having a pivot pin 71 mounted therein and extending from opposite sides thereof. The pivot pin 71 is slidably and pivotally mounted at its ends in parallel slots 73 formed in spaced connector ears 75, extending from the beam 12 adjacent the lower end thereof. The pivot pins 63 and 71 are in axial alignment with each other when the beam 12 is in its neutral roll supporting position. The cylinders 56 and 57 may be double action air cylinders and the cylinder 57 has a larger inside diameter than the cylinder 56, and the piston rod 69 extensible from said cylinder has a shorter stroke than the piston rod 61 extensible from the cylinder 56. The cylinder 57 and piston rod 69 may thus override the cylinder 56 and piston rod 61, and may act as a positioning stop for the beam 12 limiting retractible movement of the piston rod 61 and stopping the beam in the upright neutral roll supporting position shown in FIGURE 6.

When it is desired to tilt the beam 12 into a roll receiving position, with the advance retaining rails 26 forming continuations of the upper surface of the loading ramp 13 and the discharge retaining rails stopping travel of the roll of paper in position to have heads applied to opposite ends thereof upon tilting the beam to its upright neutral holding position, fluid under pressure is supplied to the head end of the cylinder and the rod end of cylinder 56. This will move the piston rod 69 to the limit of its extensible travel. The piston rod 61, however, having a longer stroke than the piston rod 69 will continue to travel and tilt the beam 12 beyond the limits of tilting movement of the piston rod 69. The trunnion pin 71 will then move along the slots 73 to the lower ends thereof. The pin 71, will then stop the beam in its roll supporting position.

In the roll receiving position of the beam 12, the piston rods 61 and 69 are extended to the full extent of their travel. In the neutral roll supporting position shown in FIGURES 2 and 6-, the piston rod 69 remains in its full extended position while the piston rod 61 is retractibly moved for half its stroke. The pin 71 on the piston rod 69 thus engages the lower end of the slots 73 and serves as a stop to properly locate the beam 12 in its roll receiving position.

When it is desired to discharge a roll from the beam 12, the piston rods 61 and 69 are moved into their fully retracted positions and tilt the beam about the axis of the shafts 20 to raise the advance rails 26 and lower the opposite rails 26, and thereby eject the roll from said beam for labeling or further processing.

The header platen has a circular periphery and an air passageway 79 leading therethrough eccentric of the center of said platen. Outwardly opening channels 77 extend angularly from the passageway 79, generally radially of the center of an intake duct 82 for a centrifugal blower 83. The blower S3 is mounted at the rear end portion of the platen 10 and extends rearwardly therefrom. The blower 83 may be a conventional form of suction blower directly driven from an electric motor 89 and has its intake duct 82 in communication with the air passageway 79, to draw air through said passageway and along the channels 77.

The platen 10 has a central recessed portion 85 having a circular periphery coaxial with the center of the duct 82 and intake for the blower 83, having a bafile plate 86 fitting thereinto and extending over the inner end portions of the channels 77. The bathe plate 86 is provided with rows of holes or orifices 88 leading therethrough into the channels 77. The blower 83 has sufiicient capacity to create a high velocity flow of air along the channels 77 under the baffie plate 86 and air inlet orifices 88, as the air flows to the blower inlet 82, and thereby creating a suction at the face of the bafiie plate 86 for holding a head to the platen for gluing to the outside of a wrapper (not shown) on a roll of paper.

The principle of holding heads to the baffle 86 and platen 10 is thus on the principle of zone of influence traction instead of straight suction, resulting in a more uniform holding of the head to the header platen 10 and the instant release of the head upon the discontinuance of operation of the blower 83.

A cable reel 90 may be mounted on one of the brackets 29 and may be connected to a source of electric power, remote from the header platens to accommodate movement of the header platens along the beam 12 toward and from the ends of a roll of paper in position to have an outside head applied thereto, in the manner previously described.

The support for the platen 10 on the upright brackets 29 is in the form of an ear 91 projecting rearwardly of said platen between the brackets 29 and secured thereto as by nuts and bolts 93, 93. The back of the platen 10- is reinforced by angular ribs behind the channels 77 and extending in the general direction of said channels angularly rearwardly from the periphery of said platen, to hold the platen from warping. Suitable heaters (not shown) may also be mounted on the back of the platen to drive a glue on the outside head after it is applied to the wrapped roll of paper.

In operation of the apparatus, the two platens it} are in their extreme outermost positions on the beam 12 and the piston rods 50 of the cylinders 51 are in their extreme retracted positions. The beam 12 and platens 1d are then tilted into a receiving position by the application of fluid under pressure to the head ends of the cylinders 56 and 57, to extend the piston rods 61 and 69 thereof for the full lengths of their strokes. A partially wrapped roll of paper rolling along the ramp 13 will then be caught and stopped by the rail 26 at-the discharge end of the beam and projecting upwardly above the surface of the ramp. The beam 12 is then tilted into its roll holding position by the application of fluid under pressure to the piston rod end of the cylinder 56 and withdrawing the piston rod 61 for a portion of the length of its stroke and holding the piston rod 69 of the cylinder 57 in its extended position. A head being in position on each header platen 10 and held thereto by the vacuum created by the blower 83, fluid under pressure may be admitted to the head ends of the cylinders 51 to extensibly move the piston rods 50 and the carriages 11 until the head platens come into engagement with opposite ends of the partially wrapped roll to press the outside heads thereto. Pressure may be maintained on the heads until the glue has had time to dry under the influence of the heating means (not shown) carried by the plates. The header platens 10 may then be withdrawn by the admission of fluid under pressure to the piston rod ends of the cylinders 51 and the roll of paper having an outside head applied thereto may be ejected from the beam 12 by the admission of fluid under pressure to the piston rod ends of the cylinders 57 and 56, retractibly moving the piston rods 61 and 69 into their full retracted positions and tilting the top surface of the beam to effect the rolling of the roll of paper therefrom along the ramp 14 for labeling, use, further processing or storage.
